Fig. 4 is the enlarged cross-sectional view of the first protruding portion 61 and the second groove 73.As shown in figure 4, the end of the first protruding portion 61
The bottom of end 56a and the first groove 73 discretely configure.In the same manner as the first protruding portion 61, the end 57a of the second protruding portion 62
Also the bottom with the second groove 74 discretely configures.
In the following, being illustrated to the movement of relay 1.When not applying voltage to coil 41, drive shaft 15 and movable iron
Core 43b be reset together spring 44 elastic force to leave direction Z2 pressing.Therefore, mobile contact piece 7 is also to leaving direction
Z2 is pressed, and as shown in (A) of Fig. 5, the first moving contact 13 and the second moving contact 14 become from 11 He of the first fixed contact
The off-state that second fixed contact 12 is left.
In addition, contact spring 17 is being configured between flange part 15a and base portion 51 under pre-compressed state.Therefore, in Fig. 5
(A) shown in when it is disconnected, contact spring 17 applies bracket 16 and flange part 15a to the direction for clamping mobile contact piece 7
Power.Therefore, the first press surface 54 of bracket 16 and the second press surface 55 are maintained at the state contacted with mobile contact piece 7.
When coil 41 is applied voltage and is excited, by means of the electromagnetic force of coil 41, movable core 43b overcomes reset
The elastic force of spring 44 and it is mobile to contact direction Z1.As a result, as shown in (B) of Fig. 5, drive shaft 15, bracket 16 and movably connect
Contact direction Z1 is mobile in the same direction for contact 7 one, the first moving contact 13 and the second moving contact 14 and the first fixed contact 11 and the
The contact of two fixed contacts 12.
In this state, using the first fixing terminal 5 and the second fixing terminal 6 limitation mobile contact piece 7 and bracket 16 to
The movement of direction Z1 is contacted, but drive shaft 15 can be mobile relative to mobile contact piece 7.Therefore, when movable core 43b by means of
When the electromagnetic force of coil 41 is further moved to contact direction Z1, drive shaft 15 is further mobile to contact direction Z1.As a result, such as
Shown in (C) of Fig. 5, contact spring 17 is pressed and shunk by flange part 15a.In this state, contact spring 17 utilizes elastic force
It exerts a force to bracket 16 to contact direction Z1.In turn, the first press surface 54 of bracket 16 and the second press surface 55 and mobile contact piece 7
It contacts and mobile contact piece 7 is pressed to contact direction Z1.
In the relay 1 of present embodiment, the first press surface 54 and the second press surface 55 and mobile contact of bracket 16
7 face contact of piece and press mobile contact piece 7.Since the first press surface 54 and the second press surface 55 have along mobile contact piece 7
The flat shape on surface therefore can inhibit when contacting with mobile contact piece 7 grinding mobile contact piece 7.Further, since the
One press surface 54 and the second press surface 55 are integrally formed in bracket 16, therefore, are able to suppress increase and the dress of manufacturing cost
Reduction with property.
First press surface 54 and the second press surface 55 are bent by a part of bracket 16 and are formed.It therefore, can be easily
Form the first press surface 54 and the second press surface 55.
First protruding portion 61 of bracket 16 is towards prominent in the first groove 73 of mobile contact piece 7.In addition, the of bracket 16
Two protruding portions 62 are towards prominent in the second groove 74 of mobile contact piece 7.Therefore, can prevent that bracket 16 from opening and from movably connecing
Contact 7 is deviate from.
The end 56a of first protruding portion 61 and the bottom of the first groove 73 discretely configure.The end of second protruding portion 62
The bottom of 57a and the second groove 74 discretely configure.Therefore, it is able to suppress due to the first protruding portion 61 and the second protruding portion 62
End 57a keeps mobile contact piece 7 ground.
An embodiment of the invention is illustrated above, but the present invention is not limited to the above embodiments, it can be
It does not depart from and makes various changes in the range of inventive concept.For example, it is also possible to change the structure of driving device 4.It can also change
Coil 41, spool 42, iron core 43, reset spring 44 or magnetic yoke 45 shapes or configure.Can also change shell 2 shape or
Configuration.
In the above-described embodiment, drive shaft 15 is pulled in by 41 side of coil by driving device 4, thus mobile contact
Piece 7 is mobile to contact direction Z1.In addition, drive shaft 15 is released from 41 side of coil by driving device 4, so as to moving contacting plate
7 is mobile to direction Z2 is left.But it is also possible in this way: drive shaft 15 is pulled in by 41 side of coil by driving device 4, thus
Mobile contact piece 7 is mobile to direction Z2 is left.It is also possible that released drive shaft 15 from 41 side of coil by driving device 4,
It is mobile to contact direction Z1 so as to moving contacting plate 7.
The first fixing terminal 5, the second fixing terminal 6, the shapes or configure of mobile contact piece 7 can also be changed.For example, the
The configuration of one fixing terminal 5 and the second fixing terminal 6 is not limited to above embodiment, can also be substituted for one another.
The shape of bracket 16 is not limited to above-mentioned embodiment, can also change.For example, in the above-described embodiment,
The quantity of press surface is two.But the quantity of press surface is not limited to two, is also possible to one or three or more.Fig. 6 is
